Lonergan says the 13th-placed Blues, who are out of finals contention with a 7-12 win-loss record, are playing without pressure.

Carlton have beaten North Melbourne and Gold Coast and lost to Fremantle by nine points in Perth in the past three rounds.

"It seems like the shackles have been released. Finals are out of reach and they're just playing footy now," Lonergan said.

"They're looking to take scalps. We're wary of that."

Lonergan said Josh Caddy, who was out for eight games before returning from a foot injury in round 14, and Allen Christensen, missing the first 13 rounds because of back surgery, had been key figures in Geelong's run of good form.
